6101. General.-During wartime there will be two conditions of readiness of the armament: Ready condition and fully ready condition. The armament may be in the ready condition when boats are under repair, secured, moored to a dock or on training runs when action with the enemy is not probable. On any occasion where action with the enemy is probable, the armament will be in the fully ready condition and partially or fully manned, depending on the circumstances and on the mission on which engaged. In placing the armament in the fully ready condition extreme care must be exercised inside the harbors or other areas where own or friendly vessels may be endangered by accidental discharge of weapons.

1. Guns clean and well oiled.
2. Oil buffers filled.
3. Head space set.
4. One thousand rounds up in each turret well cleaned and free from corrosion; not led up to gun.
5. Spare magazines loaded and at hand in tank room.
6. Waterproof cover on and secured only in wet weather. Normally off during daylight. Covers on, not secured at night.

6110. .45-caliber submachine gun-Fully ready condition.

1. Removed from stowage and in hands of gunner.
2. Magazine at hand, ready to be loaded.
3. Gun cocked; safety on.

4. Number of rounds first burst and subsequent bursts. An initial burst of 75 rounds may be fired, after which 20 rounds a minute may be fired. After waiting 15 minutes without firing, another 75 round burst may be fired. If an initial burst of only 25 rounds is fired, 25 rounds a minute may be fired continuously. The above rate of fire prevents overheating the gun, impairing its accuracy, and reducing its life. However, in combat the gun may and should be fired without regard to this.
